The ISO7221ADR is a dual-channel digital isolator from Texas Instruments, designed to provide galvanic isolation with a maximum isolation voltage of 4000V. It supports signaling rates of up to 1Mbps and operates over a wide temperature range of -40¬8C to +125¬8C. The device features TTL input thresholds and includes a noise filter to prevent transient pulses from affecting the output. It requires dual supply voltages of 2.8V, 3.3V, or 5V, and all inputs are 5V tolerant. The ISO7221ADR is characterized by low channel-to-channel output skew (1ns max) and low pulse-width distortion, making it suitable for applications in factory automation, computer peripheral interfaces, and data acquisition systems. It also offers 4kV ESD protection and is certified for safety standards including UL 1577 and IEC 62368-1.
